I did this: Checked facebook box on social setting space, filled all fields, shared pages on facebook.

I expected the plugin to do this: When sharing the frontpage insert custom description, use the default image I specified in the settings for og:image. When sharing an article, use some sort of "the_excerpt" as og:description.

Instead it did this: No og:description anywhere, and it uses latest article's og:image when sharing the frontpage.
